Question

i’m new in php and mysql
i have a problem
i have 2 tables

<?php
    $insert = mysql_query("INSERT INTO request (date, type_request, subject, customer)
    VALUES (NOW(), '".$type."', '".$subject."', '".$username."')");

    $fk = mysql_query("insert into feedback (id_request) select id_request from request where id_request = last_insert_id ");

?>

i’ve been doing that but still cannot fill the id_request in table feedback
the structure of table is like this

Table Request

id_request auto_increment not_null,-->PK
date,
type_request,
subject,
customer

Table Feedback

id_feedback auto_increment not_null,
id_request,---FK
feedback_user

can anyone give suggest how to update the foreign key

Answer 1

In your code

$fk = mysql_query("insert into feedback (id_request) select id_request from request where id_request = last_insert_id ");

replace last_insert_id with LAST_INSERT_ID()

since its a MySQL function and not a field.
